2,4-Dihydroxybenzophenone(131-56-6)

Used as UV absorber, benzophenones such as 2-hydroxy-4-methoxybenzophenone (UV-9), 2-hydroxy-4-n-octyloxybenzophenone (UV-531) derived from this product, and other monohydroxy, dihydroxy, trihydroxy, and tetrahydroxy compounds are the most widely used absorption-type light stabilizers. It can absorb ultraviolet light of 290-400 nanometers and has good compatibility with most synthetic resins. It is widely used in polymer materials. 2,4-Dihydroxybenzophenone is suitable for polyvinyl chloride, polystyrene, epoxy resin, cellulose resin, unsaturated polyester, coating and synthetic rubber. The maximum absorption wavelength Chemicalbook range is 280-340 nanometers, and the general dosage is 0.1-1%. However, the photostabilization effect of this product is not outstanding. The oral LD50 of this product for rats is 8600 mg/kg, and that for mice is 2336 mg/kg. Uses: Suitable for polyolefins, polyvinyl chloride and polystyrene. It is mainly used in plastics as a light stabilizer, which can effectively protect organic glass and cloth, prevent the material from deteriorating due to light, and is also used as an intermediate for synthesizing other ultraviolet absorbers.
